Warm the oil in a large pan over a medium heat. Add the sausages and bacon and fry for about 10 minutes until they have a nice colour. Remove the meat from the pan and set aside.
Add the sliced onions to the pan and a little more oil if necessary. Reduce the heat and fry for about 10 minutes so that the onions caramelize slowly.
When the onions have a nice colour, return the sausages and bacon to the pan and add the thyme and bay leaves. Cover with the chicken stock (broth) and return to the boil. Reduce the heat to a simmer and add the potatoes. Cook for about 30 minutes.
Add the chopped parsley and plenty of black pepper and serve.
